impl OpenAICompatibleProvider for MistralExt

const PROVIDER_NAME: &'static str = "mistral"

Provider name recorded on gen_ai.provider.name telemetry spans.

const EMITS_COMPLETE_SINGLE_CHUNK_TOOL_CALLS: bool = true

Whether the backend can emit a whole tool call (id, name, and complete arguments) in a single streaming chunk, as llama.cpp-based servers do. When true, the shared streaming layer emits such calls as soon as they arrive instead of holding them until the stream ends.

const STREAM_INCLUDE_USAGE: bool = false

Whether streaming requests include "stream_options": {"include_usage": true}. Providers that reject unknown parameters and already report usage on the final chunk set this to false.

type StreamingUsage = Usage

The usage payload parsed from streaming chunks and carried on the final streaming response. OpenAI’s Usage for most providers; providers with richer usage accounting (e.g. Mistral’s cached-token fallbacks, DeepSeek’s cache hit/miss counters) substitute their own.

type Response = CompletionResponse

The chat-completions payload this provider returns.

fn completion_path(&self, _model: &str) -> String

The request path for chat completions, resolved against the client base URL by Provider::build_uri. Providers that route the model through the URL (e.g. Azure deployment paths) or keep other capabilities on differently-versioned paths override this. model is the identifier the completion model handle was created with; per-request model overrides only affect the body.

fn finalize_request_body(&self, body: &mut Value) -> Result<(), CompletionError>

Adjust the fully serialized request body — after any streaming parameters are merged — immediately before it is sent. This is where wire-level dialect differences live (e.g. Mistral’s "any" tool choice, DeepSeek’s string-flattened message content).

const SUPPORTS_TOOLS: bool = true

Whether the provider supports tool calling. When false, tools and tool_choice are dropped with a warning during request conversion — before tool-choice validation, so unsupported tool configurations never error client-side on a provider that ignores tools anyway.

const SUPPORTS_RESPONSE_FORMAT: bool = true

Whether output_schema maps to OpenAI’s response_format. Providers whose APIs reject json_schema response formats set this to false; the schema is then dropped with a warning instead of being sent.

fn build_completion_request( &self, model: String, request: CompletionRequest, options: CompletionModelOptions, ) -> Result<CompletionRequest, CompletionError>

Build the typed chat-completions request. Providers that share the OpenAI transport but need provider-specific message conversion can override this while still using GenericCompletionModel for sending, streaming, error handling, and telemetry.

fn prepare_request( &self, request: &mut CompletionRequest, ) -> Result<(), CompletionError>

Adjust the typed request before serialization (e.g. rewrite the model identifier or fold provider-native tool definitions out of additional_params).

fn finalize_request_body_with_options( &self, body: &mut Value, options: CompletionModelOptions, ) -> Result<(), CompletionError>

Adjust the fully serialized request body with model-level options. Providers that do not need model-instance options should override finalize_request_body instead.

fn decorate_streaming_tool_call( &self, detail: &Value, tool_calls: &mut HashMap<usize, RawStreamingToolCall>, )

Decorate streamed tool calls from provider-specific streaming detail payloads. Most OpenAI-compatible providers do not emit such details.

impl Provider for MistralExt

const VERIFY_PATH: &'static str = "/models"

Provider endpoint used by VerifyClient to validate credentials.

type Builder = MistralBuilder

The builder type that constructs this provider extension. This associates extensions with their builders for type inference.

fn build_uri(&self, base_url: &str, path: &str, _transport: Transport) -> String

Build a complete request URI for the given base URL, provider path, and transport.

fn with_custom(&self, req: Builder) -> Result<Builder, Error>

Apply provider-specific request customization before sending.
